Answer:
380
Explanation:
I couldn't find the answer anywhere so this is the correct answer. I got it graded.
First, we have to write a balanced equation for the production of ammonia (NH₃) from hydrogen gas (H₂) and nitrogen gas (N₂):
N₂ + 3H₂ → 2NH₃
Now, the mole ratio of H₂ : NH₃ is 3 : 2 based on the coefficients of the balanced equation.
If the moles of H₂ = 15 moles
then the moles of NH₃ produced = (15 mol ÷ 3) × 2
= 10 mol
Thus, the number of moles of NH₃ produced when 15 mol of hydrogen gas is combined with excess nitrogen gas is 10 mol.

Explanation:
Balanced chemical equation for reaction of hydronium ions with calcium carbonate will be as follows:
2H3O+ (aq) + CaCO3 (s) => Ca2+ (s) + 3H2O (l) + CO2 (g)
In this balanced chemical equation, acidic aqueous solution of hydronium ion (H3O+) reacts with calcium carbonate salt (CaCO3) resulting in the formation of calcium cation (Ca2+) an alkali, that results in neutralization of excessive acid. It also forms liquid water (H2O) along with liberation of carbon dioxide gas (CO2). All acids stronger than hydrogen carbonate, provide their calcium salts dissolved in water yielding carbon dioxide, because a bare hydrogen ion has no chance of surviving in water.
To balance this chemical equation, 2 molecules of hydronium ions react with 1 molecule of calcium carbonate resulting in formation of 1 molecule of calcium cation, 3 molecules of water and 1 molecule of carbon dioxide. The reaction proceeds at room temperature.
